ALMALINUX9.2:CLSA-2025:1751142973 advisory.

  - Git is a source code management tool. When cloning from a server (or fetching, or pushing), informational
    or error messages are transported from the remote Git process to the client via the so-called sideband
    channel. These messages will be prefixed with remote: and printed directly to the standard error
    output. Typically, this standard error output is connected to a terminal that understands ANSI escape
    sequences, which Git did not protect against. Most modern terminals support control sequences that can be
    used by a malicious actor to hide and misrepresent information, or to mislead the user into executing
    untrusted scripts. As requested on the git-security mailing list, the patches are under discussion on the
    public mailing list. Users are advised to update as soon as possible. Users unable to upgrade should avoid
    recursive clones unless they are from trusted sources. (CVE-2024-52005)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
